1. create a file with name “Profile.ps1” under %windir%system32WindowsPowerShellv1.0profile.ps1

2. Add following content to the file.

# Adds the base cmdlets
Add-PSSnapin VMware.VimAutomation.Core
# Add the following if you want to do things with Update Manager
#Add-PSSnapin VMware.VumAutomation
# This script adds some helper functions and sets the appearance. You can pick and choose parts of this file for a fully custom appearance.
. “C:Program FilesVMwareInfrastructurevSphere PowerCLIScriptsInitialize-PowerCLIEnvironment.ps1”

You need administrator permission to create file on the system32 location.

There are lot of articles introduce vSAN feature and steps by steps guide. I referred William Lam’s article & Duncan’s article to configure vSAN on my lab, I was true I exactly followed his steps to configure the vSAN, but I can not saw anything under disk field under Disk Management.

Please note: Following steps does not work for ESXi 6.0 RC on VMware Workstation 10. You have to set scsix:y.virtualssd = 0 in vmx file to mark the disk as non-SSD. Please refer to William’s article for detail.

Initially, I thought that disk marked as SSD since I ran command to enable SSD. Actually it’s not like that, it shows SSD since my hard disk is SSD!!!! I don’t have to run the command introduced in the articles to turn SSD on, it’s nature SSD. lol

What I need to do is actually totally oppositely. That’s the steps I used to enable vSAN:

1. Create two disks.

2. Login ESXi hosts by SSH.

3. Run following command, find out the two disks you want to use for vSAN. Record runtime name.

NTP service is very important for troubleshooting, vmkernel log timestamp is incorrect if your NTP service is not running and ESXi system time is wrong. It can also impact to VM system time even you disable time synchronization on VMware Tools since VM still need to sync time with ESXi after awake from suspended status, finish vMotion, or revert from snapshot.

I know it’s simple to configure NTP services on single how, what if you want to configure NTP service on massed hosts?
